camera preview is stretched pretty much in this layout #16
Description
Hi again
I've been busy with your library this past couple of days and unfortunately, I faced another problem
I have this layout file:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="match_parent"
android:layout_width="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#00000000"
android:layoutDirection="rtl">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:titleTextColor="@android:color/white"
android:background="?attr/colorPrimary">
<TextView
android:id="@+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="title"
android:textColor="@android:color/white"
style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_gravity="center"
android:typeface="monospace"/>
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:layoutDirection="ltr"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:layout_gravity="center_horizontal"
android:background="#ebeff2"
app:tabMode="scrollable"
app:tabGravity="fill"
app:tabIndicatorColor="@android:color/black"
android:id="@+id/tabLayout_categories"
style="@style/MyCostumeTabLayout"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:layoutDirection="ltr"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="@+id/viewPager_tabs"
android:layout_gravity="center"/>
</LinearLayout>
<!-- this is the root layout for the barcode scanner -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/frameLayout_camera_root" />
</FrameLayout>
As you can see I did this so that the barcode scanner is on top of other layouts. ( I am trying to make this layout look like a dialog)
this is my java code and how I start the barcode scanner (for now this code is in the onCreate method of the activity):
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_barcode);
showBarcodeScanner();
}
private void showBarcodeScanner() {
prepareBarcodeScanner();
getSupportFragmentManager().beginTransaction().add(R.id.frameLayout_camera_root, barcodeCaptureFragment).commit();
}
private void prepareBarcodeScanner() {
barcodeCaptureFragment = BarcodeCaptureFragment.instantiate(
MVBarcodeScanner.ScanningMode.SINGLE_AUTO, formats);
scanningListener = new BarcodeCaptureFragment.BarcodeScanningListener() {
@Override
public void onBarcodeScanned(Barcode barcode) {
//do something
}
@Override
public void onBarcodesScanned(List<Barcode> barcodes) {
}
@Override
public void onBarcodeScanningFailed(String reason) {
}
};
barcodeCaptureFragment.setListener(scanningListener);
}
the problem is that with this method, the camera preview is stretched (it still captures the barcodes and all, but the barcode is not on the screen at all when it is being captured, since the preview is stretched).
So how can I fix this?
